Notes on Using the Battery Pack
Before using the battery pack, read the following precautions for correct use.

About the battery pack

The battery pack built in your VAIO computer is not removable.
For safety reasons, battery charging may be suspended at higher or lower temperatures.
The battery pack is not fully charged at the time of delivery.
While the battery pack is in use or being charged, heat builds up in the battery pack. This is
normal and is not cause for concern.
About battery discharge
After battery charge, the battery pack will gradually discharge over time even while not in use.
If it is left unused for an extended period of time, the battery power may be depleted. It is
recommended that you recharge the battery pack before use.

About battery life

Battery life varies depending on usage and settings.
About battery deterioration and replacement
The battery pack is consumable. The capacity gradually declines through repeated cycles of
recharging and discharging, and depending on the ambient temperature during use or
storage. As a result, the battery life becomes short even if it is fully charged and eventually
the battery pack reaches the end of its life.
If the battery pack quickly runs out of power after being fully charged or it has reached the
end of its life, replace it with a new one.
Contact an authorized Sony service/support center and replace the battery pack with a new
one specified by Sony.
When the battery pack is running out of power
If the battery pack runs out and your VAIO computer is not plugged in, power will be cut off
and any data you are working on will be lost.
While your VAIO computer is running on battery power, save data frequently.
